It's important to know that the life expectancy of a pressure tank is about 10 -15 years.
Common Signs of a Well Water Tank Problem
Unstable water pressure as the pump cycles on and off. A pump that runs less than 30 seconds to pressurize the tank. A pump that cycles on and off frequently or remains running. Water leaks at the pressure tank.
A well pressure tank typically lasts between 5 to 15 years, depending on maintenance, water quality, and usage frequency. Key signs that a well pressure tank needs replacement include water pressure fluctuations, unusual noises, and visible leaks.
Replacing a well pressure tank costs $500 on average, but it can cost between $300 and $700, depending on the tank's size, capacity, and labor costs for professional installation.
Chances are it's time to replace your water well pressure tank. While this may sound like a job for a professional plumber, this is also something you can do yourself at home if you're handy with DIY plumbing.
To ensure that your pressure tank is properly maintained and continues functioning correctly—as well as provide water at consistent pressure throughout your home—you should have it checked every year.
A failed pressure tank bladder can be very hard on the well pump's electric motor over time, and it can drastically reduce the pump's life expectancy, so as soon as you hear a noise, call a qualified plumber to inspect your well pump.
A: A rule of thumb method used by Water Worker and other sources is to add up all the water outlets inside and outside the house. Toilets, faucets, washer, showers, etc and then multiply by 3 for the gal capacity of the tank. Example 10 outlets times 3 = 30 gal. Round up so a 33 gal tank.
Find your well tank's pressure gauge (usually small, black, round, and located at the bottom of the tank). Check to see how the tank's pressure cycling is configured—either on a high (40/60 psi) or a low (30/50 psi) cycle. You can check this by having your partner run cold water from a tap for a few minutes.
How Do I Know When My Pressure Tank is Too Old? We know what you are thinking. You would love to squeeze a few more years out of the tank and just replace that rusty “T” pack, and not the tank itself. It's important to know that the life expectancy of a pressure tank is about 10 -15 years.
The tanks should be flushed semi-annually to remove accumulated sediments by opening the tank drain valve. These sediments could harbor and shield harmful microbes from chlorination should the well and home plumbing system require disinfection.
With proper well maintenance, your new well pump can last, on average, 8 to 15 years, though many homeowners report their pumps lasting far longer, often between 20 and 30 years!
If your water is clean and you're using the right size tank, the average life-span is around 15 years.
No, a larger well pressure tank won't increase water pressure by itself. However, there are other benefits to having a bigger tank. Namely, larger tanks have longer run times and require less cycling from your pump than smaller ones.
Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi.
Desired pressure range
30–50 psi: Standard for most homes with moderate water demand. 40–60 psi: Provides higher pressure for large homes, multi-story houses, or homes with high water demand.
Storage Volume
A small (50- to 60-gallon) storage tank is usually sufficient for one to two three people. A medium (80-gallon) storage tank works well for three to four people.
The 20 gallons are almost always too small and tend to be “contractor specials”. You are ALWAYS better having a larger tank than a smaller one. This chart shows how many gallons of water is really inside your storage tank. This assumes a pressure setting of 40/60.
Well pumps are still able to function without a pressure tank, but it's highly recommended to install a pressure tank because they increase the lifespan of your well pump. Well pumps aren't designed to operate rapidly or continually; when this happens, they tend to engage in something called water cycling.
Checking the pressure in your pressure tank should be done at least once per year. Even though your tank should never loose pressure, this simple check will make sure everything is functioning properly.
It will not only improve the performance of your well system, but it will also save you money in the long run by avoiding the need for costly repairs. Taking the time to properly prepare your well pressure tank for the addition of air is a small task that can make a big difference.
Eventually the sediment fills to the top of the inlet pipe and increased amounts flow in the stream of water. (Figure 1) The increased volume will clog filters sooner than what has been experienced. Draining or “blowing down” the tank will help rid the tank of this accumulation.
